Leaders of the Group of Seven (G7) nations plan to tighten sanctions on Russia at their summit in Japan this week, with steps aimed at energy and exports aiding Moscow's war effort, said officials with direct knowledge of the discussions, Azernews reports citing Reuters.

New measures announced by the leaders during the May 19-21 meetings will target sanctions evasion involving third countries, and seek to undermine Russia's future energy production and curb trade that supports Russia's military, the people said.

Separately, U.S. officials also expect G7 members will agree to adjust their approach to sanctions so that, at least for certain categories of goods, all exports are automatically banned unless they are on a list of approved items.

The Biden administration has previously pushed G7 allies to reverse the group's sanctions approach, which today allows all goods to be sold to Russia unless they are explicitly blacklisted.
